Thanks for explanation scott.

 

No problem. Basically I look at the soundings, srfc winds and 950mb winds and temps. need the instability in the lower levels. Convergence of wind vectors at the srfc and sometimes visible at 950 are indications of a CF. There will be one here...but it's not a classic one.

I'm seeing a strong banding signal modeled. If you look at 700mb winds and VVs...you see what looks like a narrow area of strong VVs and wind convergence. This is frontogenesis. This goes from DC through ern CT and ern MA. You figure this is slanted NW, so areas just NW of this are in the game too if this feature is correct.

Thank you for the tutorial.

Maybe our friends in Central ma and Connecticut get into some more widespread accumulations this time

 

 

The soundings in this system look better than the Jan 2-3 system....the snowgrowth layer goes from the surface to about 600mb.

 

I think this is a widespread deal. The mid levels look great.
